To all whom it may concern: 4

Be it known that I, ALBERT C. Wmcox, a citizen of the United States,residing at Wheeling, in the county of Ohio, State of West Virginia,have invented certain new and useful Improvements in Glass-BlowingApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to glass blowin apparatus and particularly toapparatus 0 this type employed in the production of what is commonlyknown as paste ware.

The object of the invention resides in the provision of an apparatus ofthe character named which embodies a rotatable carrier and a pluralityof corresponding glass blowing devices mounted upon the carrier each ofwhich is adapted to be operated to effect one complete blowing operationthrough the medium of means which is set.

in operation by the application of a blow pipe thereto, such applicationof a blow pipe also serving to render active means for.

imparting a partial rotation to the carrier.

A further object of the invention resides in the provision of a glassblowing apparatus of the character named Which embodies improvedstructure for effecting the cooling of the molds of the various glassblowing devices during the rotation of the carrier.

Broadly speaking the object of the invention resides .in the provisionof a glass blowing apparatus which will'produce uniformly perfect ware,which is capable of.an exceedinglv large output ofproduct, and whichwill require a relatively small amount of attention during its operationwith resultant economy and correspondingly large profits incident to itsuse.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and com bination of partsto be hereinafter more fully described and particularly pointed out i inthe appended claims.

Referring to the drawings the apparatus is shown as comprising a basebearing 40 about which is arranged a concentrically disposed frame Aincluding a track 41. The ends of the frame A are connected by anarcuate tank 42, which is also disposed concentric with the base bearing40. The track 41 is extended to traverse the tank 42 and that portion ofsaid track disposed within the limits of the tank 42 is directeddownwardly as at 43, it being noted that this arrangement of the track41 renders same continuous or endless. Rotatably supported by thebearing40 is a column 44 the upper end of which is reduced as at 45 and justbeneath the reduced portion 45 said column is threaded as at 46 for apurpose that will presently appear. Fixed on the column 44 is a circulartable 47 having a downwardly this instance as four similar heads are embodied in the apparatus illustrated. The

periphery of the make and break device B is engaged by a contact finger52 suitably mounted on the adjacent wall of the tank 42. Fixed on thecolumn 44 between the hub 48 and bearing 40 is a sprocket wheel 53 for apurpose that will presently appear.

Mounted upon the upper end of the col-' umn 44 is a collar 54 from whichradiate four arms- 55 arranged in diametrically opposite pairs with theadjacent arms disposed at right angles to each other.'- Each of the arms55 is provided intermediate its ends with a bearing 56 and rotatablymounted in each of the bearings 56 is a vertical shaft 57. Looselymounted on the upper end of each shaft 57 is a worm wheel 58 which hassecured to its lower side a crown gear 59. The outer end of each arm 55has formed integral therewith a bearing 60and slidable in this bearingis a pipe 61 which carries on its lower end a slip joint 62 of a typefully described in U. S. Letters Patent #1,029,779 granted to me June18, 1912. Pivoted on each arm 55 is a two-arm lever 63 which is providedintermediately with a laterally and upwardly directed arm 64. One end ofthe lever 63 is connected by a link 65 with the adjacent slip joint 62while the 105 other end thereof carries a balancing weight 66. Mountedupon each of the arms 55 is a horizontally disposed circular track 67arranged concentrically to the adjacent shaft 57 and provided on itsupper side with a notch 68 for a purpose that will presently appear.Fixed on each shaft 57 between the track 67 and the adjacent crown gear59 is a hub 69 from which radiate spokes 70 and 71, said spokes carryingat their 115 outer ends an arcuate track 72 disposed concentric to theadjacent shaft 57. The spokes 70 and 71 are connected by a web 72disposed over the track 67 and provided with a vertical passage 73 thelower portion of which passage is enlarged to form a shoulder 74.Mounted in the passage 73 is a clutch locking bolt 0 which embodies alower socket member 75 in which is slidably mounted a pin or bolt 76.The pin or bolt 76 is provided with a transverse passage 77 throughwhich extends a bridge pin 78 having its terminals connected to thesocket member 75. It will be noted that the passage 77 is considerablywider than the di- 13 ameter of the bridge pin 7 8 so that the pin orbolt 76 is capable of limited movement in the socket member 75 as willbe obvious. A spring 79 is interposed between the inner end of the pin76 and the base of the socket of the member 75, said spring serving tonormally hold the pin 78 against the inner side of the passage 77whereby the pin or bolt 76 will normally be capable of a limitedmovement inwardly of the socket member 75. Encircling the pin or bolt (6is a spring of greater strength than the spring 70. This spring 80 bearsat one end against the socket member 3'5 and at its other end againstthe shoulder 74 and serves to yield ingly hold. the lower end of thesocket member 75 into engagement with the track 67.

The structure by which the worm wheels 58 of the various heads of theapparatus are simultaneously and continuously rotated embodies brackets81 and 82 which carry respectively horizontal bearings 83 and 84, saidbearings being disposed in parallel relation. Rc-tatably mounted in thebearing 83 is a shaft 85 which has fixed on respective ends thereofworms 86 meshing with adjacent worm wheels 58 respectively. Rotatablymounted in the bearing 84 is a shaft 87 which has fixed on the terminalsthereof respectively worms 88 meshing with adjacent worm wheels 58.Mounted upon the reduced portion 45 of the c lumn 44 is a bracket 89 andsupported by this bracket is an electric motor 90. Fixed on the shaft ofthe motor 90 is a sprocket wheel 91. Projecting laterally from thecollar 54 is a stub shaft which rotatably supports a sleeve 92. Fixed onthis sleeve 92 is an inner sprocket wheel 93 and an outer sprocket wheel94. Traveling on the sprocket wheels 91 and 93 is a sprocket chain 95.Fixed on the shaft 85 in line with the sprocket wheel 94 is a sprocketwheel 90 and traveling on the sprocket.

wheel 94 and the sprocket wheel 95 is a sprocket chain 97. Fixed on theend of the shaft 85 remote from the sprocket wheel 96 is a sprocketwheel 98 which alines with a sprocket wheel 99 fixed on the shaft 87 andtraveling on the sprocket wheels 98 and 99 is a sprocket chain 100. Bythis construction it will be obvious that upon actuating the motor 90all of the worm wheels 58 will be rotated in the same direction.

The arm 64 of each lever 63 carries an gaging pin 101 which is adaptedto engage the under side of the track 72 during a part of each rotationof the shaft 5?. It will be apparent that when the pin 10. 1 is inengagement with the track 72 the associated slip joint 62 will be heldelevated. On the other hand when thepin 101 passes out engagement withthe track 72 the slip joint 6.2 will descend under the influence ofgravity to its lowermost position and remain so 7 the apparatus.

disposed until the track 72 again moves into engagement with the pin101.

blidably mounted on the column 44 is a sleeve 102 provided at its lowerend with oppositely disposed alined openings 103. Engaged on the threads46 and extending through the openings 103 is an adjusting nut 104. ItWill be obvious that this nut 104 serves to support the sleeve 102against downward movement the column 44 under the influence of gravityand it will be further obvious that through the instrue mentality ofsaid nut the sleeve 102 and the parts supported by the sleeve to behereinafter referred to can be readily adjusted to different elevations.Carried by and radiating from the sleeve 102 are arms 105 correspondingin number to the arms 55 and disposed in the same vertical plane ascorresponding arms 55. Each of the arms 105 is provided at anintermediate point with a bea'ring106 alined with the bearing 56 of thecorresponding arm 55, said bearings 56 and 106 both serving to rotatablysupport the shaft 57 of the corresponding head of Mounted on the outerend of each arm 105 and disposed in longitudinal alinement with said armis a forked member 107 including arms 108 and 109, the former arm beinglonger than the latter and between these arms the blow pipe 110 of thecorresponding head of the apparatus is seated during the operation ofsaid head. Fixed on each shaft 57 above the arm 105 is a segmental gear111 which during the rotation of the shaft 57 passes across the innerends of the arms 108 and 109 in position to operatively engage a pinion112 fixed on the blow pipe 110 and effect the rotation of the blow pipe.The advance end of the gear 111 is provided with an upwardly extendinglug 113 upon the upper end of which is piv oted for movement in ahorizontal plane an arm 114. Pivotal movement of this arm 114 in thedirection of rotation of the gear 111 is prevented by means of adownwardly directed finger 115 on the rear end of the arm 114 and heldin abutting relation to the lug 113 by means of a spring 116. /Vhen tl1e arm 114 is disposed in its normal position it lies in substantiallyradial relation Lo the shaft 57.

Pivotally mounted on the underside of the arm 108' is a latch 117 whichis normally held in engagement with a stop pin 118 also carried by thearm 108 by means of a spring 119. The end of the latch 11'? projectingbetween the arms 108 and 109 is provided with a cam edge 120 which isengaged by the blow pipe 110 during the insertion of the latter betweenthe arms 108 and 109. This engagement of the blow pipe with the cam edge120 will swing the latch 117 on its pivot so as to permit thefullinsertion of the blow pipe against a bearing 121 carried at theinner ends of the arms 108 and 109. As soon as the blow pipe has beeninserted the proper distance between the arms 108 and 109 the spring 119will operate to return the latch 117 to its normal position so as tolock the blow pipe 110 against accidental disengagement from itsposition between the arms 108 and 109. It will be noted however that theconstruction of the latch 117 is such that the manual disengagement ofthe blow pipe from between the arms 108 and 109 will not be interferedwith. The position of the forked member or blow pipe holder 107 is suchthat when a blow pipe is associated therewith it will be disposed inlongitudinal alinement with the slip joint 62 of the correspondinghead-of the apparatus so that when said slip joint is lowered it willreceive the upper end of the blow pipe to connect the latter with theair supply. Fixed on the column 44 beneath the sleeve 102 is a collar122 from which radiate arms 123 corresponding in number to the arms 105and also being correspondingly disposed. Each of the arms 123 carries atits outer end a bearing 124 in which rotates the lower end of theshaft57 of the corresponding head of the apparatus.

Mounted upon the table 47 is a plurality of parallel spaced pairs ofribs 125, corresponding to the number of heads of the apparatus andbeing positioned substantially in the planes of respective heads. Theouter ends of the ribs 125 terminate in depending ears 126. Pivotallymounted between the ears 126 of each'pair of ribs 125 is a'lug 127 whichdepends from an intermediate point on a platform 128 whereby when saidplatform is d sposed in horizontal position the inner portion thereofwill be engaged upon the upper side of the table 47 and between the ribs125. Depending from the outer end of ea ch platform 128 are spacedtransversely disposed ears 129 between which is journaled a roller 130engaged upon the upper side of the track 41 and adapted to travel uponthe latter continuously during the rotation ofthe apparatus as willhereinafter appear. Rising from each platform 1.28 adiacent the outerend thereof is a pin 131 and pivotally connected through the medium ofthis pin are sections 132 and 133 of a two-part mold. Mounted upon theinner end of each platform '128 is a cylinder 134 having slidablymounted therein a piston 135 including oppositely disposed leather cups136 and 137. Secured to this piston 135 is a piston rod 138 which isslidably engaged through the forward end of the cylinder 134. Theforward end of the cylinder 134 is provided with an air vent 139, whilean air supply pipe 140 is. engaged through the rear end of the cylinderfor the purpose of delivering compressed air to the interior thereof.The forward end of the piston rod 138 exteriorly of the cylinder hasmounted thereon a cross arm 141 and the terminals of this cross arm areconnected to respective mold sections 132 and 133 by means of links Deach of which comprises sections 142 and 143 connected together in amanner to permit relative longitudinal adjustment thereof. Through themedium of this adjustment of the links D it will be obvious that a thesections 132 and 133 can always be maintained in correct relation foreffecting the proper closing thereof. It will be noted that the weightof the mold at the outer end of the platform '128 is considerably inexcess of the structure mounted on the inner end of said platform andfor this reason it will -be apparent that during the rotation of theapparatus 1 the platforms and molds will move successively downwardlyand transversely through the tank 42 and be subjected to the coolinginfluence of the liquid con tained in said tank, said platforms beingreturned to horizontal position by reason of the engagement of therollers 130 with the track 41. As the platforms 128 are returned tohorizontal position the ribs 125 serve to guide and hold same in properposition to dispose the mold in correct vertical alinement with respectto the blow pipe irrespective of any wear that may arise in the pivotalconnection between the platform and said ribs.

Mounted upon the upper end of the column 44 is a tubular member 144having its bore reduced and threaded as at 145 and the portion of itsbore disposed above the reduced portion 145 flared as at 146. EX-tending through the tubular member 144 adiacent its lower end is an airsupply pipe 146. This pipe is carried upwardly through the bore of saidmember and has one end thereof threaded in the reduced portion 145 ofsaid bore. Rotatably mounted on the tubular member 144 is a sleeve 147having a lower lateral flan e 148 and an upper lateral flange 149.Threaded in the sleeve 147 is an eye member 150 through theinstrumentality of which the sleeve is adapted to be connected with asuitable fixed part ad-- jacent the apparatus whereby the sleeve is heldagainst rotation on the tubular member 144 but permitting free rotationof said I tubular member within the sleeve. Mounted in the flange 149 atdiametrically opposite points respectively are bolts 151 and 152 andslidable upon these bolts is a joint member circling the bolts 151 and152 respectively are springs 158 which hear at their upper ends againstthe bridge plate 156 and at their lower ends against the member 153 saidsprings serving to hold the tapered portion 154 of the member 153 in theflared portion 146 of the bore of the member 144. By this constructionit will be apparent that the air supply through the pipe 146 will beconstantly maintained during the rotation of the member 144 and duringthe rotation of the entire apparatus. Fixed on the tubular member 144beneath the sleeve 147 is a collar of insulating material 159 and fixedupon this collar 159 are conducting rings 160,-

161 and 162. Secured to and depending from the flange 148 is an arm 163formed of insulating material. Mounted in this arm 163 are contactscrews 164, 165 and 166 which engage respectively with the conductingrings 160, 161 and 162. Leading from the conducting rings 160, 161 and162 are wires 167, 168 and 169 respectively. These wires are in turnconnected with binding sc ews 170 respectively which are mounted on ablock of insulating material 171 carried by the member 144 at the lowerend of the latter. By this construction it will be apparent thatsuitable current can be supplied to the electrical devices moving withthe apparatus without the necessity of the source of said current alsomoving with the apparatus.

Mounted on the column 44 beneath the collar 122 is a collar 172' fromwhich radiate arms 173 corresponding in number and position to the arms123. Each of the arms 173 carries at its outer end a forked member 174which is disposed in vertical alinement with the corresponding forkedmember 107, said forked members 107 and 17 4 serving to hold the blowpipe 110 in proper alinement with the slip joint 62 and the mold of thecorresponding head of the apparatus. Mounted upon each arm 17 3 at theinner end thereof is a three-way valve 175 which is operated through themedium of a handle 176. Each valve 175 is connected to the interior ofthe corresponding cylinder 134 by the pipe 140 and to the atmosphere bya passage 177. Each valve 17 5 is also connected to the air supply bymeans of a U-shaped distributing pipe. 178, which latter pipe isconnected to a vertically extending pipe 179, said pipe 179 uniting withthe pipe 146 at 180. A valve 181 is included in the pipe 179 forcontrolling the How of air therethrough. By this construction it will beapparent that when the valve 175 is in the position shown in Fig. 24 airwill pass therethrough to the pipe 140 and be delivered into thecylinder 134 of the corresponding head with the result that the piston135 will be driven to the forward end of the cylinder and the associatedmold sections 132 and 133 moved to closed position. is operated to theposition shown in Fig. 23 it will be apparent that the air at the rearof the piston 135 will be exhausted to the atmosphere and the moldsections 132 and 133 automatically moved to open position through themedium of springs 182 attached to respective mold sections at one endand at their other ends to arms 183- carried by the platform 128 ofthecorresponding head. This operation of the valves 17 5 for the purposeof opening and closing the molds is automatically accomplished duringeach As soon as the waive blowing operation of the various heads of theapparatus in a manner and through the medium of a structure to be nowreferred to.

Depending from each arm 123 is a U shaped member 184 and slidablyengaged through the arm connecting portion of said U-shaped member andthrough a suitable passage in the arm 123 is a rod 185 the upper end ofwhich is forked'and has rotatably mounted thereon a roller 186.Adjustablv mounted on the rod 185 within the U-shaped member 184 is acollar 1'87 and encircling the rod 185 is a spring 188 one end of whichbears against the collar 187 and the other end against the armconnecting portion of the U-shaped member 184. This spring constantlytends to hold the rod 185 at the limit of its upward movement, suchlimit beingdetermined by a collar 189 adjustably mounted on the rod 185and adapted to engagethe outer side of the arm connecting portion of theU-shaped member 184. The lower end of the rod 185 is connected to thefree end of the handle 176 by means of a link 190. By this constructionit will be apparent that when the rod 185 is moved downwardly asufficient distance the valve 175 will be operated to'admit air to thecylinder 134 of the corresponding head and thus operate the moldsections of said head to closed position. As soon as the rod 185 isreleased the spring 188 willoperate to raise said rod and move the valveto the position shown in Fig. 23 when the mold 'sections of thecorresponding head willbe moved to open position through the medium ofthe springs 182, such movement of the mold sections also serving toreturn the piston 135 to the rear end of the cvlinder 134. The d wnwardmovement of each rod is automatically accomplished during the operswitch193 mounted on one side of the U- shaped member 184. This knife switch193 includes the usual pivoted arm 194 and fork 195 which receives thearm 194 to close the switch in the usual and well known manner.

out of the fork 195 and the switch maintained open. On the other handwhen the rod 185 is moved downwardly by the rotation of the track 191 itwill be obvious that the arm 194 will be moved into the fork 195 and theswitch closed. Each of the switches 193 is included in a circuitforminga component part of the mechanism for effecting the intermittentrotatlon of the apparatus so as to present the various heads of themachine to the operators successively.

In order to supply air through the pipes 61 to the various blow pipes ofthe machine, the pipe 179 is extended bevond'its connection with thepipe 146 and then connected to a U-shaped distributing pipe 196 which issubstantially concentric to the tubular member 144. The extremities ofthe pipe 196 are provided with T-joints 197 from which lead branch pipes198 to respective pipes 61 of the "arious heads of the machine. Y

The mechanism for effecting the intermittent rotation of the apparatusembodies a vertical shaft 199 rctatably mounted in the frame A. Looselymounted on this shaft 199 is a gear 200 and a ratchet wheel 201, saidgear and ratchet wheel being connected through the medium of a commonhub 202. Fixed'upon theshaft 199 above the ratchet wheel 201 is a collar203 provided with oppositelv disposed radiating arms 204 each of whichcarries at its outer end a spring controlled pawl 205 adapted forcooperation with the ratchet wheel 201. Fixed on the shaft 199 above thecollar 203 is a sprocket wheel 206 which is disposed in alinement withthe sprocket wheel 53 mounted on the column 44. Traveling on thesprocket wheels 53 'and 206 is a sprocket chain 207 through theinstrumentality of which the rotation of the shaft 199 will be impartedto the column 44 and of course to the various heads of the apparatussupported by the column. Suitably mounted adj acent the shaft 199 is acylinder 208 in which is slidably mounted a piston 209. Connected tothis piston and slidably engaged through the forward end of the cylinder208 is a piston rod 210 the end of which disposed exteriorly of thecylinder 208 terminates in a toothed rack 21.2 which operatively engagesthe gear 200. A pipe 213 communicates with the interior of the cylinder208 at the rear end of'the latter while a corresponding pipe 214communicates with the front end of the cylinder at the forward cylinderto the atmosphere. will result in the piston 209 being driven end of thelatter. The pipes 213 and 214 are mutually connected by a pipe 215' inwhich is included a valve 216 for controlling the supply and exhaust ofair to and from opposite ends of the cylinder 208, said valve 216 beingoperatively connected with a pipe 217 leading from a suitable compressedair supply (not shown). The valve 216 is provided with a handle 218which is pivotally connected at its free end with the core 219 of asolenoid 220. Mounted on one end of the solenoid 220 is a pocket or cap221 in which is seated a spring 222 which constantly bears against theadjacent end of the core 219 to normally hold said core in the positionshown in Fig. 20. Assuming the solenoid 220 to be energized the core 219will occupy the position shown in Fig. 19. As the core 219 is connectedwith the handle 218 the valve 216 will be operated by the inwardmovement of the core 219 so as to adinit air to the rear'end of thecylinder 208 and exhaust air from the forward end of the This statusforward which will cause the gear 200 and the ratchet wheel 201 torotate to the left. During this rotation of the ratchet wheel 201 thepawls 205 will engage the teeth of said ratchet wheel and transmit therotation of the latter to the shaft 199 and sprocket wheel 206 and therotation of this sprocket wheel will in turn be transmitted by thesprocket chain 207 and sprocket wheel 53 to the column 44. thus rotatingbodily the various heads of the apparatus. As soon as the solenoid 220is deia'nergized the spring 222 will operate to move the core 219 to theposition shown in Fig. 20. This movement of the core 219 will positionthe valve 216 tov admit compressed air to the forward end of thecylinder 208 and exhaust air from the rear end of said cylinder to theatmosphere with the result that the piston 209 will be driven rearwardlyand the gear 200 and ratchet wheel 201 rotated to the right. During thislast named rotation of the ratchet wheel 201 the pawl 205 will ride overthe teeth of said ratchet wheel and no rotation will be imparted to theshaft 199 or the sprocket wheel 206.

The wiring by which the circuit which energizes the solenoid 220 isconveyed can be best described by' referring to Fig. 31 wherein thesource of said circuit is indicated at 223 from the positive pole ofwhich leads a wire 224. This wire 224 is connected to the contact screw164, said screw engaging the conducting ring 160 as previously referredto. This conducting ring 160 is in turn connected by the wire 167 to theupper binding screw 170 in Fig. 15. From this binding teams forkelements 195 of the switches 193 are connected respectively to thecontact plates 51 of the make and break device B by means of wires 227.Leading from the contact finger 52 is a wire 228 which is connected tothe solenoid 220, said solenoid being also connected to the negativepole of the source 223 by means of a wire 229. The motor 90 iscontrolled by means of line, armature and shunt wiring operativelyconnected with a starting box or rheostat 230 in the usual and wellknown manner, the circuit for operating-the motor 90 also emanating fromthe source 223.

In the operation of the apparatus the head thereof on the extreme rightin Figs. 1 and 3 is ready to receive a blow pipe from the operator,while the head on the extreme left has completed the operation ofblowing and is ready to have the blow pipe and ware carried therebyremoved. The uppermost head of the apparatus in Fig- 3 is in operation,while the lowermost head inFig. 3 is idle and the mold thereof isdisposed Within the tank 42 as shown in Fig. 7. In the head ofthe aparatus disposed at the extreme right in Figs. 1 and 3 the clutchmechanism is in the position shown in Figs. 26, 27 and 28, the blow piperotating gear in the position shown in Fig. 16 and the cam track of themold opening and closing mechanism in the position shown in Fig. 21

as is likewise the remainder of said mecha nism. In applying a blow pipeto the head of the apparatus on the extreme right of Figs. .1 and 3 thepipe is first moved into engagement with the long arms of the forkmembers 107 and 174 and then shoved along these arms toward the bearing121. During this movement of the blow pipe same will engage the inneredge of the arm 114 and impart a partial rotation to the gear 111 andthe shaft 57. As soon as the blow pipe is fully inserted in the forkedmembers previously referred to the pinion 112 will mesh with the teethof the gear 111 and thelatch 117 will position itself to hold the blowpipe in place. The partial rotation of the gear 111 and the shaft 57caused by the application of the blow pipe between the arms 108 and 109will in turn eflect a partial rotation of the segmental track 72 and thespokes supporting same which carry the clutch bolt 0. As the lower endof the clutch bolt C is disposed in "the notch 68 of the track 67 itwill be obvious that said bolt as it is moved out of the notch 68 willrise upwardly and engage the crown gear 59 so as to connect the shaft 57with said gear and cause the rotation of the latter to be im-' parted tosaid shaft. At the moment the clutch bolt C is engaged with the crowngear 59 the track 72 will pass out of engagement with the pin 101 andthe slip joint 62 will descend upon the upper end of the blow pipe 110.Upon the institution of the rotation of the shaft 57 the cam portion 192of the track 191 will engage the roller 86 and force the rod 185downwardly to operate the valve 175 for the purpose of admitting air tothe rear of the cylinder 1341 and operate the pgsgton 135 to close themold sections 132 and The downward movement of the rod 185 ust referredto will close the switch 193 and a circuit will be established throughthe wire 22 1, ring 160, wire 167, binding screw 170, wire 226, switch193 of the operating head of the apparatus, wire 227 leading fromsaid-switch, contact plate 51, contact finger 52, wire 228, solenoid220, wire 229 and thence back to the source 223. This circuit willenergize the solenoid 220 and move the parts from the position shown inFig. 20 to the position shown in Fig. 19 which will result in an outwardstroke being imparted to the rack 212 and this stroke of said rack willrotate the column 44 and the heads of the-machine until the nextinsulating projection 50 comes in contact with the contact finger 52when the circuit will be broken, solenoid 220 deenergized and the partsreturned to the position shown in Fig. 20. The momentum of the apparatuscarries the insulating projection 50 slightly over the contact finger 52thus leaving the parts properly set to effect the necessary rotation ofthe apparatus upon the operation of the succeeding head thereof. Beforethe shaft 57 shall have made one complete revolution the track 72 willagain engage the pin 101 and elevate the slip joint 62 and atsubstantially the same time that the elevation of the slip joint takesplace the gear 111 will pass out of engagement with the pinion 112 andthe rotation of the blow pipe'llO will cease as will likewise theblowing operation. At the time of the disengagement of the gear 111 fromthe pinion 112 the roller 186 will pass out of engagement with the track191 and the valve 175 will be operated to exhaust the air from thecylinder 13 1 and permit the mold sections to move to open position. Theswitch 193 will be opened simultaneously with the operation of the valve175 just referred to. The rotation of the shaft 57 will then continueuntil the various parts have been properly positioned to institute thenext operation of the head. lVhen this status has been produced thenotch 68 of the track 67 will aline with the clutch bolt 0 sothat saidbolt will move downwardly into the notch and become disengaged from thecrown gear 59 thus terminating the rotation of the shaft 57.

It will be noted that the gears 111 are splined upon respective shafts57 whereby said years may be adjusted vertically on said shafts. Inorder to hold the gears 111 in a desired adjustment there is mountedrendering the carrier moving means active.

in the hub of each gear a binding screw 231. By adjusting the collar102, arm 105 and gear lllvertically it will be obvious that theapparatus can be adapted with facility for use in connection withdifferent sizes of molds, such adjustment positioning the lower ends ofthe blow pipes at a greater or less elevation.

It will be noted that when the shaft 57 has made one complete revolutionif the blow pipe of the associated head is not removed from its holderthe advance edge of the arm 114 will engage the blow pipe but as saidarm is free to swing on its pivot in a direction opposite to thedirection of rotation of the gear 111 it will partake of such pivotalmovement and' damage to parts obviated. As soon as the blow plpe isremoved under these conditions the arm 114 will return to the positionshown in Fig. 16. Reverting to the clutch bolt C it will be obvious thatin the event of the end of the pin 7 6 engaging the outer end of a toothof the crown gear 59 when the clutch is thrown in the spring 79 willyield until the pin 76 is positioned between adjacentteeth of the crowngear when said pin will be forced between the teeth. In this waybreakage of the pin 76 and interference with the throwing in of theclutch is avoided.
